Instance and Static functions

[Jomy10]

Consider the following struct:

struct Dog {
    name: String
}

Declaring functions (methods)

declaring a function (method) for this struct could go in one of the following ways (not sure which one is best)

Extending the struct

ext Dog {
    func bark() {}
}

With a reference

func (dog &Dog) bark() {}

Discusion

I think ext (as in extend) might be cleaner, but (dog &dog)` is more explicit and forces you to use the variable in your function, making for much cleaner code (no accessing variables directly that belong to the struct)

Static vs instance

My current idea is the following:

func StaticFunc() {}
func instanceFunc() {}

So calling these would look like this:

let dog = Dog()
dog.bark() // instance method
Dog.IsAnimal() // Static method

I really like this idea as it makes it very explicit that IsAnimal is a static method (like you would have Dog::isAnimal() in Rust and dog.bark())

Another idea would be the following syntax:

func IS_ANIMAL() {}

I'm not sure what is the best.
